To all whom it may concern:

ta] limb laterally in position.

Be it known that I, THOMAS ALEXANDER BOYD, a subject of the King of Great Britain and Ireland, and a resident of Glasgow, county of Glasgow, Scotland, have invented Improvements in Rings and Travelers for Spinning and Analogous Machines.

My invention refers to rings and travelers such as are'used in spinning, twisting, and such like machines, and has for its object their better working, lubrication, and more convenient manipulation.

In the accompanying drawings, Figure 1 represents an elevation in cross-section of my preferred form. Fig. 2 is a plan view of. the same. Fig. 3 is a modification in sectional elevation. Fig. 4 is a plan view of the form shown in Fig. 3. Fig. 5 is another modification in sectional elevation.- is a plan view of the same. Fig. 7 represents a modification in sectional elevation, showing a lubricating means that may be applied to any of the modifications; and Fig. 8 is a plan view of the form shown in Fig. 7. 1

The first part of my invention consists of -a ring-traveler which works upon a short tube or ring. The traveler has a horizontal limb which works upon the lower edge of the ring. From the horizontal limb there rises an upright limb which passes up through the ring and is formed at its upper end to receive the thread. The horizontal limb is enlarged at both ends or has the ends turned u ward to catch on the outside of the lower 0 ge of the ring lor the purpose of keeping the horizontal limb laterally on the ring. In some cases we turn the ends of the horizontal limb downward, and in such cases we form the plate referred. to hereafter, which is below the traveler, with an edge or rim standing upward, so that the ends of the horizontal limb shall bear on it and so keep the'horizon- The upper end of the traveler is free to ress against the inside of the ring by eentri ugal force when working or to be drawn toward the spindle by the thread. The two ends or feet of the horizontal limb are preferably made a distance apart equal to one-fourth the circumference of the ring upon which they work, so as to prevent locking. This art of my invention includes a plate place below the lower edge of the ring sulliciently to allow the traveler to revolve around the ring for the purpose of keeping the traveler from dropping away from the ring. This plate Fig. 6

is made movable downward or sidewise to permit the travelerto pass onto the ring.

a ring 3 and a traveler 4, and having a late 5 suiticiently below the ring 3 and trave er 4 to allow the latter to work freely around the ring 3. The ring3 is a short tube rounded at its lower edge 3, which projects below the ring-holder 1 to permit the traveler 4 to work around it. 'lhering-holder 1 is chambered on its under side 1 for the same purose. On the under side of the holderthere is also formed a circular recess 1 eccentric to the ring. In this recess I place a plate 5, resting on the ring-rail 2. Ihi's plate 5 has a hole 5 central with the ring large enough to clear the bobbin or co being spun, but less in diameter than the ring-3, so as to prevent the traveler '4, which works on the lower edge 3 of the ring3, from dropping cit. I form on the plate 5 a tail 5 projecting through; an opening in the eccentric'chamber to the front of the ring-rail 2. permits the plate 5 to receive about onefourth of a revolution, and being eccentric externally to the ring 3 the hole 5 concen trio to the ring 3 is carried sufiicien'tly to one side to allow the traveler 4 to be hooked aroundthe lower edge 3 of the ring 3. The plate 5 is then moved to its original position with its center-hole 5 true to the ring 3, and thus it keeps the traveler 4 in its place. I form a traveler 4 of a piece of round" steel wire, like the letter T inverted. The horizontal limb 4 of the traveler 4 lies between the plate 5 and the bottom edge 3 of the ring 3. The ends 4 of the horizontal limb 4 are turned upward, so as to embrace the outside of the lower edge 3' of the ring 3. The horizontal limb 4 of the traveler, with the upturned feet 4 is made in length equal to about one-fourth the circumference of the ring 3, so as to revolve freely without looking around the ring 3.

From a point preferably nearer to the lea ingend of the horizontal limb 4 of the traveler 4 I form an upright limb 4 passing through the ring 3 and having a hook 4" turned outward and downward, but clear of the top 3' of the ring 3 to receive the thread. The traveler 4 presses against the inner side of the ring 3 by centrifugal force when working, but is free to swing inward toward the spindle by the pull of the yarn. It will thus be understood that The opening the ring 3 and traveler 4 sufficiently to allow a hole 10 through the ring-rail and the ring l the traveler is held on the ring 3 by the up- I turned feet 4 bearing on the outside of the E lower edge 3 of the ring 3 and by the upright limb bearing on the inside of the ring 3, and as the traveler is drawn around the ring 3 by the thread it drags the thread. \Vhen, however, the drag becomes excessive, the thread i draws the upper end of the traveler from off the ring, and thus relieves the drag. In a second arrangement, Figs. 3 and 4, of this part of my invention I employ a ring 3 and traveler 4, similar to those described above. I fix the ring 3, however, in a ring-rail 6, and on the bottom side 1 secure at one side by two screws a thin metal plate 7 with a hole 7 central to the ring to clear the bobbin or cop. This plate 7 is sulliciently clear of the under edge of the ring 3 and the traveler 4 so as to allow latter to work freely, and being held at one side only may be pressed downward from the traveler 4 to be hooked onto the ring 3. In a third arrangement of this the first part of my invention I employ, Figs. 5 and 6, a ring-traveler 8, similar to the traveler described above, but'with the ends 8 of the horizontal limb 8 turned downward to en gage on the plate 9 below the traveler 8. For this purpose the plate 9 is formed with an upstanding edge 9 around the central hole in plate. The downturned feet 8 of the horizontal limb 8 of the traveler 8 work on the outside of the upstanding edge 9 on the lower plate, and these keep the horizontal limb laterally in position.

The seconl part of my invention refers to the lubrication of rings and travelers and consists in forming on the ringhol;ler or ringrail a chamber to contain lubricant with means of forcing the sail lubricant into the rail to lubricate the ring and traveler. In carrying out this the second part of my inven- E tion in one arrangement, Figs. 7 and S, I employ a ring-traveler 4 anl plate 7 below the ring 3, as described in the foregoing second i arrangement of the first part of my invention. I fix the said ring 3 in a ring-rail 10, 1 upon which I form a chamber 10 with a l screwed plug 10 From the chamber I bore 3 and by means of the screwed plug I force the lubricant into the ring.

I claim as my invention- 1. In spinning and analogous machines,

the combination 0 a ring with a traveler hav- 1 ing the shape of the letter T inverted, with its two horizontal limbs adapted to extend across and work on the lower edge of the said ring, and equal in length to about one-fourth the circumference of the ring, the ends of the said horizontal limbs being formed with extensions to keep-the traveler laterally in position, the said traveler having its upright limb with. its upper end made to receivethe thread and free to press on the inside of the ring by centrifugal force or to swing toward the spindle by the pull of the thread.

2. In spinning and analogous machines,

the combination of a ring with a traveler having the shape of the letter T inverted, with its horizontal limbs adapted to extend across and work under the edge of the said ring, and extensions at the ends of said horizontal limbs to keep the traveler in position laterally, the said traveler having its upright limb adapted to receive the thread, and to press against the inside of the ring by centriiugal force.

3. In spinning and analogous machines, the combination of a ring with a traveler having the shape of the letter T inverted, with its horizontal limbs adapted to extend across and work under the edge of said ring, extensions on said limbs, means engaged thereby for keeping the traveler in position laterally, the said traveler having its upright limb to receive the thread, and a readily-ad justable plate below said ring adapted to be moved for placing the traveler on the ring.

4. In spinning and analogous machines the combination of a ring with a traveler having the shape of the letter T inverted, with its,

horizontal limbs adapted to extend across and work under the ed e of the said ring, and extensions at the enr s of said horizontal limbs to keep the traveler in position laterally, the said traveler having its upright limb adapted to receive the thread and to press against the inside of the ring by centrifugal force, together with a chamber containing lubricant and means for forcing the said lubricant into the ring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
